Popular reads where the reactions are: ditto, nos.lol, primal, ours

Measured: ditto held 94% of distinct reactions (and keeps a month of
them); damus capped asks at ~300, pruned in a day and added nothing.
Everything (raw firehose) gets its own list without damus (empty answer
to a bare kind-1 ask) or ditto (~30% Mostr-bridged posts). A saved list
equal to the old or current defaults follows the defaults.
